'Cream of the crop' Ninja water bottle that keeps drinks hot for 8 hours is now 43% off

The water bottle from Ninja Kitchen has £15 knocked off its price and has a star rating of 4.6

Ninja is at the top of its game when it comes to kitchen appliances - from air fryers to ice cream makers. But its stainless steel water bottles have also received high praise and as the Amazon Prime Deals Days begins, the retail giant has vastly reduced the cost of the bottle that is 'worth every penny' by 43%.

Usually retailing at £34.99 on Ninja Kitchen, the Ninja Thirsti Water Bottle and Flask now costs £19.99 and is the currently number one best-seller in Amazon's Insulated Bottles category and it's clear to see why. It even keeps ice intact for for two days.

A key detail that is ideal for commuters and those on the go is that the lid is leakproof and has been built with a rubber gasket to ensure the lid remains secure with no pesky trickles down your hand. Plus, its neat size fits into most car cup holders.

With a medium volume of 700ml, the Ninja Thirsti comes in a variety of different colours from mint green to black and has been made with triple-vacuum insulation to ensure your tea remains hot for eight hours on end and your cold water frosty for over 24 hours.

If you're more into fizzy alternatives, this bottle has been designed with carbonated drinks in mind so you can remain safe in the knowledge that with its smooth stainless steel interior, your fizzy water will remain 'spritzy' for hours on end as the bottle's make-up reduces nucleation points. Its silicone handle makes it easy to drink from too - and has extra grip making it ideal to take running, walking and jogging - and its 'round spout' top 'adds comfort when drinking'.

It's been a hit with shoppers looking for a sturdy water bottle with a glistening 4.6-star rating and many stating that this bottle is worth 'every penny'. One raved how it 'really does keep your drink cold all day' and said: "This Ninja Thirsti bottle is worth every penny.

"It really does keep your drinks cold all day. It is well made and seems hardy, plus it doesn't leak at all. It looks good and is a great size. Both my husband and son have one each and they think they are great! There are no negatives. I would highly recommend this drink bottle to anyone."

Another - who had invested in a handful of other water bottles before finding the Thirsti - added: "I love this water bottle. Having spent what I would conservatively estimate to be hundreds of pounds on various water bottles over the years, I can hand on heart say that this one is the cream of the crop.

"The Ninja name is attached to it so you do get some peace of mind knowing it’ll be a high-quality product. I’ve owned it for a few months now. No leaks, no spills, no dents from dropping it. Keeps my water cold for over 24 hours. I only use it for chilled water.

"I’m very happy with the product, have noticed people getting bottle envy on the train when I’ve whipped it out and had a sip and some colleagues have asked where I got it from when I’ve been using it at work. Wish I’d seen this years ago."

A third simply hailed: "Amazing bottle. Took on holiday. Filled with loads of ice and water. Tried with prosecco and beer ... it stayed fizzy." Although the vast majority of comments are praising this water bottle for its ability to keep drinks at optimal temperature and durability, a select few were left 'disappointed' when their hot drinks didn't stay quite as hot for the eight hours stated.

One said: "Not the standard I was expecting from Ninja, barely warm after 6 to 7 hours." They added: "I wish I had bought the Stanley version." While this wasn't an issue for many others, one shopper said the bottle was 'almost perfect' and reflected: "The only downfall with this bottle is I would like to have a 1 hand opening option rather than having to unscrew the top to have a drink."

That being said, the overall consensus is: "This bottle is excellent value for money. It's the drink bottle I've been waiting for."
